Pricing and delivery have been excellent

Comments about 3/4" Wilkins 950XL Double Check Valve Assembly:

I've needed replacement valves but have limited manufacturer selection in my area. Direct replacement equipment saves on retrofitting. You're pricing has been a no brainer. Even with shipping costs, I still save money. Thanks.

    Q:

    Can this product be used outdoors in a cold (freezing) climate?
    Is there a process for winterizing this valve?

      A:

      Ryan,
      I do not run irrigation in the winter during freezing temps. I shut off the supply and drain pressure off the demand side off the valve as part of my 'winterizing' the irrigation system.
      I installed mine below grade in an irrigation box. I didn't like the above ground as it was an eyesore to the landscaping. With the double-check valve you can install below grade in most counties (check with your municipality about their requirements before purchasing).
      We live in NC and get freezing temps, but I've had no issues. If you want to install above grade and use in freezing temps you'll have to insulate the valve and use a well-insulated cover (box or decorative rock cover).

      A:

      You need to take the valve inside during the winter before the temperature
      dips below freezing. The valve is meant to be installed on the between the
      water supply (just after the water meter and a shutoff valve) and your
      irrigation system (or some other system). Turn the shutoff valve off before
      removing the the back flow valve. Its that easy. I usually evacuate the
      pipes that attach to this valve to just below the frost line.

      A:

      I have successfully used an insulation bag for the past two years on my
      double check valve system. It is situated outdoors and has been subjected
      to freezing temperatures during that time. As for winterizing the valve,
      that I have not done.

    Q:

    sales engineer, will this model be compliant with most EPA agencies as a back-flow prevent-er. our village currently requires a dual check valve for new installations. our IEPA does not consider the dual check valve points worthy because it cannot be checked.

      A:

      No, according to EPA this valve assembly will not comply with their standards. This valve meets ASSE® Listed 1015 and EPA requires ASME B16.34-1996.
